3 myp chemistry atomic structure
The document discusses atomic structure and the development of atomic theory. It explains that:
1) All matter is made of tiny indivisible particles called atoms, as proposed by Democritus in ancient Greece.
2) Laws of conservation of mass and constant composition provided evidence supporting atomic theory by showing matter is neither created nor destroyed in chemical reactions.
3) Atoms are composed of even smaller subatomic particles - electrons orbiting a dense nucleus of protons and neutrons, held together by electrostatic attraction. The identity of an element is determined by its number of protons.

Atoms and molecules
Atoms are the smallest particles that make up all matter. Molecules are formed when two or more atoms bond together. Ions are formed when atoms gain or lose electrons, acquiring an electric charge. Chemical formulas represent the composition of molecules and ions in terms of the symbols of their constituent elements.
Atoms and molecules
1) An atom is the smallest unit of matter that has the properties of an element, composed of a dense nucleus surrounded by orbiting electrons.
2) A molecule is a group of two or more atoms bonded together through attractive forces.
3) The law of conservation of mass states that mass can neither be created nor destroyed in a closed system. The law of constant proportions states that a chemical compound always contains the same proportion of elements by mass.
2 contribution of john dalton martin
John Dalton's atomic theory proposed that all matter is composed of extremely small indivisible particles called atoms. He hypothesized that atoms of the same element are identical, while atoms of different elements differ in their properties. Dalton also suggested that atoms combine in fixed ratios to form compounds. His atomic theory provided an explanation for laws such as the law of conservation of mass and the law of definite proportions. Dalton's experiments helped establish the idea that atoms are the basic building blocks of all matter.

The document discusses the structure of atoms. It describes John Dalton's model of indivisible atoms and J.J. Thomson's model with a positive sphere and negative electrons. Ernest Rutherford proposed a model with protons and neutrons in the nucleus and electrons orbiting it. Neils Bohr proposed electron shells, and James Chadwick discovered neutrons in the nucleus. Atoms have protons, neutrons, and electrons. The number of protons determines the element. Isotopes have the same number of protons but different neutrons. Electron configuration involves filling shells with a maximum of 2, 8, 8 electrons.
Henry moseley atomic number
Henry Moseley discovered the relationship between an element's atomic number and the wavelength of its x-ray emissions. This led to a better arrangement of the periodic table and allowed scientists to predict and later synthesize new elements in the laboratory. Moseley arranged the elements according to the square root of the x-ray frequency, which more correctly predicted periodic trends. The invention of the cyclotron provided accelerated particles that could bombard heavy nuclear targets to synthesize new elements through nuclear reactions. One of the first artificially made elements was technetium, produced by bombarding molybdenum with deuterons. Many transuranic and superheavy elements have since been synthesized using similar nuclear reaction methods.

Atoms, Molecules, And Matter
An atom is the smallest particle of an element that contains protons, neutrons, and electrons. Elements are substances made of a single type of atom that combine to form molecules, which are made of two or more atoms joined together. Molecules such as water, written as H2O with two hydrogen atoms and one oxygen atom, are the smallest particles that combine without chemical change to form all matter in the world.
Atomic theory of matter
The document discusses the early discoveries that led to the modern atomic theory, including Thomson's discovery of the electron in 1897, Rutherford's experiments with radioactive elements which established that atoms have a small, dense nucleus, and Rutherford's gold foil experiment in 1911 which demonstrated that the mass and positive charge of atoms are concentrated in a tiny nucleus rather than uniformly distributed as previously thought. These experiments revealed that atoms are made up of a small, positively charged nucleus surrounded by electrons and established the basic structure of atoms that forms the basis of modern atomic theory.
Atomicstructure
The document outlines the evolution of atomic structure models from early ideas to modern understanding. It discusses early thinkers like Democritus who proposed atoms as fundamental units of matter. John Dalton later proposed his atomic theory which stated that atoms are indivisible and cannot be created or destroyed. J.J. Thomson's discovery of the electron through deflection experiments in a cathode ray tube provided evidence that atoms contain smaller subatomic particles, contradicting Dalton's ideas. This led to proposals of early atomic structure models like the plum pudding model.
Atoms and molecules
This document contains information about chemical laws, atoms, molecules, ions, and formulas. It begins with acknowledging its sources and stating its educational purpose. It then defines the laws of conservation of mass and constant proportions established by scientists. Later sections explain atoms and their properties according to Dalton's atomic theory. It also describes molecules as groups of bonded atoms and provides examples. Ions are defined as charged particles in compounds of metals and nonmetals. The document concludes with multiple choice questions.

The document summarizes key ideas from a chemistry chapter on the structure of the atom. It discusses how ancient Greek philosophers like Democritus and Aristotle attempted to explain matter. John Dalton later revived the idea of atoms in the early 1800s based on his scientific experiments. The document also outlines the discovery of subatomic particles like protons, neutrons, and electrons, and how this led to models of the structure of the atom. It describes how atoms can be unstable and undergo radioactive decay by emitting radiation like alpha, beta, or gamma particles.
Classification of elements & periodicity in properties
The document discusses periodic trends in properties such as atomic radius, ionization energy, and electronegativity. It explains Mendeleev's periodic table and how modern periodic law arranges elements based on atomic number instead of atomic mass. Periodicity in properties occurs because similar electronic configurations repeat at regular intervals as atomic number increases. Atomic radius generally decreases across a period as nuclear charge increases, and increases down a group as more shells are added. Ionization energy is the energy required to remove an electron from an atom, and is directly proportional to nuclear charge and inversely proportional to size and shielding effects.

The document discusses the importance and history of the periodic table. It explains that the periodic table organizes the chemical elements and provides order that was lacking prior to its development. Dmitri Mendeleev created one of the first periodic tables by arranging elements by atomic mass, with similar reacting elements in columns. The current table is organized by atomic number. Elements in the same group have similar properties because they have the same number of valence electrons. The document outlines several important families of elements on the periodic table, including their properties and significance.

Hydrocarbons
Organic chemistry is the study of carbon-based compounds. Organic compounds usually contain carbon-carbon and carbon-hydrogen bonds. Hydrocarbons are the simplest type of organic compound, composed entirely of carbon and hydrogen. There are several types of hydrocarbons including alkanes, alkenes, alkynes, and aromatic compounds like benzene. Alkanes contain only single bonds, alkenes contain double bonds, and alkynes contain triple bonds.

2 myp Chemistry states and energy
The document discusses the kinetic theory and states of matter. It explains that all matter is made up of tiny particles in constant motion. The three states of matter - solid, liquid, and gas - can be explained by how strongly the particles are attracted to each other and how much freedom of movement they have. Solids have particles fixed in position that can only vibrate. Liquids have particles that can move around more freely, vibrating, rotating, and translating. Gases have particles that are very weakly attracted and have complete freedom of movement. Phase changes occur when the energy content and motion of particles changes, such as when a substance is heated or cooled.

It discusses key topics like the development of the early atmosphere from volcanic gases, the formation of oceans, early life in the oceans, and the current atmosphere composed primarily of nitrogen and oxygen. It also defines chemistry as the study of matter and its properties, and categorizes pure substances and mixtures. The last section provides sample questions to test understanding.
3. Pwpt The Atom
This document discusses the structure of atoms using helium and xenon as examples. It notes that both are atoms but xenon has a greater mass because it contains more subatomic particles. The three main subatomic particles are identified as protons, neutrons, and electrons. A helium atom is drawn showing its structure of two protons, two neutrons, and two electrons. Isotopes are defined as atoms that have the same number of protons but different numbers of neutrons. Atomic number identifies the element based on its number of protons, while mass number includes both protons and neutrons. Atomic mass is calculated as a weighted average of the masses and abundances of an element's isotopes.
InChI vs IUPAC nomenclature: Aspects to be aware of when using Standard InChI
Features of IUPAC nomenclature that cannot be represented in Standard InChI will be examined to draw caution to cases where the use of standard InChI (and even in some cases non-standard InChI) may result in a loss of information. These areas include the representation of tautomers and mixtures of stereoisomers.
History of periodic table
The document summarizes the history and development of the periodic table. It describes early models proposed by Dobereiner, Newlands, and Meyer. It explains that Mendeleev is considered the "father" because he left gaps for undiscovered elements and his predictions were later verified. The table became more accurate when Moseley determined elements were arranged by atomic number instead of mass. Later discoveries by Seaborg expanded the table with new elements.

Chapter 4
This document discusses the structure of atoms. It begins by defining an atom and outlining Dalton's atomic theory. It then explains that atoms are composed of subatomic particles like electrons, protons, and neutrons. The nucleus contains protons and neutrons, while electrons orbit around the nucleus. Different elements are distinguished by their atomic number, which is the number of protons. Isotopes are atoms that have the same number of protons but different numbers of neutrons. The average atomic mass takes into account the relative abundances of isotopes in a naturally occurring sample of an element.
C4 lesson part two
1. Ionic compounds form when a metal reacts with a non-metal, resulting in positively charged metal ions and negatively charged non-metal ions that bond together in a crystalline lattice structure.
2. When ionic compounds dissolve in water or melt, the ions become free to move and conduct electricity. During electrolysis, positively charged metal ions move to the cathode and negatively charged non-metal ions move to the anode.
3. Common ionic compounds include sodium chloride, formed from sodium and chlorine ions, and copper chloride, used in electrolysis to extract copper metal from its ionic form.
Atomic Theory.pptx
The atomic-molecular theory of matter states that all matter is composed of small, fast-moving particles called atoms that can join together to form molecules. This theory has developed over thousands of years through the works of scientists like Democritus, Dalton, Thomson, Rutherford, Bohr, Chadwick, and others who proposed and tested successive atomic models. The current model depicts atoms made up of a small, positively charged nucleus surrounded by a negative electron cloud.

Atoms are the fundamental units that make up elements. John Dalton proposed the atomic theory which states that elements are made of atoms and atoms of the same element are identical. Atoms are made up of a nucleus containing protons and neutrons, surrounded by electrons. The discovery of the electron, proton, neutron, and development of quantum theory led to modern atomic structure and periodic table. The periodic table organizes elements based on atomic structure including atomic number and trends in properties.

This document discusses the chemical components that make up cells. It begins by explaining that all matter is made up of combinations of elements, which are substances like carbon and hydrogen that cannot be broken down further. Atoms are the smallest particles of elements that retain chemical properties, and molecules are formed by atoms linking together through chemical bonds. The document then discusses the basic structure of atoms, including protons, neutrons, and electrons. It explains that the outermost electrons determine how atoms interact and form different types of chemical bonds, such as ionic bonds formed by electron transfer and covalent bonds formed by electron sharing. These bonds link atoms together into molecules that make up living cells and organisms.

- Discovery of additional subatomic particles like protons and neutrons led to the
Atoms and molecules best presentation
The document discusses the structure of atoms and various atomic models proposed over time. It begins by defining an atom as the smallest particle of an element consisting of protons, neutrons, and electrons. J.J. Thomson's cathode ray experiments discovered electrons. Rutherford's alpha particle scattering experiments showed that atoms have a small, dense nucleus. Bohr proposed discrete energy levels to explain the stability of atoms. Later, the neutron was discovered, completing the standard atomic model with protons and neutrons in the nucleus and electrons in shells or orbits around the nucleus.

The document summarizes the development and key features of the periodic table. It traces how early scientists like Newlands and Mendeleev organized the elements and developed periodic trends. The modern periodic table is arranged by atomic number and contains metals, nonmetals, and metalloids organized into blocks and groups. Elements in the same group have similar properties due to their electron configurations, and properties vary periodically according to trends like atomic radius and ionization energy.

Chapter 4 atomic structure
Democritus first proposed the idea of atoms in ancient Greece. John Dalton later established atomic theory based on experiments. Atoms are made up of subatomic particles including electrons, protons, and neutrons. Ernest Rutherford's gold foil experiment in 1911 revealed that atoms have a small, dense nucleus containing protons and neutrons, with electrons in empty space around the nucleus. Isotopes are atoms of the same element with different numbers of neutrons, giving them different atomic masses. The atomic number identifies an element based on its number of protons, while the mass number includes both protons and neutrons.
